JSR D10F porting - UEFI does not boot

[S-trace]

Hello.

I'm trying to port EFIDroid for JSR D10F phone, but fastboot boot out/device/jsr/d10f/uefi_boot.img just hangs up device.

It does not boot on "stock" (really, it is custom CAF-based LK) bootloader, and it does not boot on fastbooted lk.img built after finalize_device
Last log message is "Booting linux @ 0x8000, ramdisk @ 0x2000000 (0), tags/device tree @ 0x1e00000".
Fastboot booting usual Android boot image produces exactly same log line (except for ramdisk size, which is not 0 for it).

What did i wrong?

Thank you.
